To Multiply: You do not line up the factors by the decimal. Instead, place the number with more digits on top. Line up the other number underneath, at the right. Multiply Count the number of decimal places (from the right) in each factor. Use the total number of decimal places in your two factors to place the decimal in your product.
Example: 5.63 x x two one three.
Example: 0.53 x has more digits (4) than 0.53 (3), so it goes on top x Decimal Places three two five.
Try This: 6.5 x x one two.
